On the contrary: it's one less exception to remember.  With this change,
the lexical syntax of type variables and type constructors is exactly
the same as that for data variables and data constructors respectively,
except that there are some special type constructors (->), (), (,,), etc,
just as there are some special data constructors like 1.7, (), (,,) etc.
